Paul was very vocal in advocating the early church. He was a missionary. He even penned down the majority of the Word. 

In the midst of all of these works he was asking for prayer for himself. He needed people to pray that he would be bold in opening his mouth, in spreading the gospel. 

Essentially he was relying completely on God to continue to use him. In Jesus, Paul found his strength.

That same Jesus wants to use us. Let us be bold like Paul and take our petitions before God. Ask for courage. He alone is the one to provide strength, opportunities and blessings.
